Abstract

A superconducting magnet supporting and positioning system comprises a refrigerator (1), a low-temperature container (2), a cold conducting band (3), a superconducting solenoid coil (4), an upper suspension magnet (5), a side upper positioning magnet (6), a side lower positioning magnet (7), a lower suspension magnet (8) and connecting rods (9). After the superconducting solenoid coil (4) is electrified, electromagnetic repulsion is generated between the upper suspension magnet (5) and the lower suspension magnet (8) and the superconducting solenoid coil (4) to enable the superconducting solenoid coil (4) to be suspended in the air, and electromagnetic repulsion is generated between the upper side upper positioning magnet (6) and the side lower positioning magnet (7) and the superconducting solenoid coil (4) to enable the superconducting solenoid coil (4) to be positioned and free of declination. No heat contact exists between the magnets and the superconducting solenoid coil, so that transmission heat leakage of the superconducting solenoid coil can be reduced, and power of the needed refrigerator can be lowered.

Description

technical field [0001] The present invention relates to superconducting magnets. Background technique [0002] Superconducting magnet technology is widely used in various fields such as the development of the national economy and military industry. Its application goes deep into medicine, electric power, scientific experiments and national defense military industry, etc., and it plays an increasingly important role in national construction. [0003] Superconducting magnets need to operate at a very low temperature before they can be energized and operated. Generally, there are two ways to keep superconducting magnets at low temperature: liquid helium immersion refrigeration and refrigerator conduction cooling. Because liquid helium is expensive and mainly depends on imports, its widespread use is greatly limited; in recent years, conductivity cooling technology has developed rapidly, and superconducting magnets can be cooled to low temperatures or even lower than the tempera...
